Aglaonema plant named ‘TWYAG0035’

ABSTRACT

A new  Aglaonema  plant particularly distinguished by having foliage that is dark green and variably marked with pale pink coalescing spots and blotches, primary veins that are white and flushed with pink, midrib that are white and variably tinged with pink, small, densely leafy and compact plant habit and yellow-green spathes, is disclosed.

Genus and species: Aglaonema hybrida.

Variety denomination: ‘TWYAG0035’.

BACKGROUND OF THE NEW PLANT

The present invention comprises a new and distinct cultivar of Aglaonema, botanically known as Aglaonema hybrida and hereinafter referred to by the variety name as ‘TWYAG0035’. The new variety originated from an open pollination made in Bogor, West Java, Indonesia between unknown individual plants of Aglaonema (species unknown). The new variety was discovered as a single plant within the progeny of the stated open pollination in a controlled environment in Bogor, West Java, Indonesia.

The new variety was created in Bogor, West Java, Indonesia and has been asexually reproduced repeatedly by vegetative cuttings and tissue culture in Apopka, Fla. for two or more generations. The present invention has been found to retain its distinctive characteristics through successive asexual propagations.

SUMMARY OF THE INVENTION

The following are the most outstanding and distinguishing characteristics of the new variety when grown under normal horticultural practices in Apopka, Fla.

-   -   1. Foliage that is dark green and variably marked with pale pink         coalescing spots and blotches;     -   2. Primary veins are white and flushed with pink;     -   3. The midrib is white and variably tinged with pink;     -   4. Small, densely leafy and compact plant habit; and     -   5. Yellow-green spathes.

DESCRIPTION OF THE PHOTOGRAPH

This new Aglaonema plant is illustrated by the accompanying photograph which shows the overall plant habit and leaf color. The colors shown are as true as can be reasonably obtained by conventional photographic procedures.

DESCRIPTION OF THE NEW VARIETY

The following detailed description sets forth the distinctive characteristics of ‘TWYAG0035’. The data which define these characteristics were collected from asexual reproductions carried out in Apopka, Fla. The plant history was taken on 12 month-old plants started from a single four-leaf rooted cutting, still in a vegetative state and grown in Apopka, Fla. Rooted cuttings were planted in 15 cm pots and grown in a greenhouse in February 2007. The plants were pinched twice. Color readings were taken under natural light. Color references are primarily to the RHS Colour Chart of the Royal Horticultural Society of London (RHS) (2001).
